DUAL SHIELD B9

DUAL SHIELD B9

Dual Shield B9 is an all-position flux cored electrode designed for the welding of modified 9% chromium creep resisting steels, such as ASTM A335 Grade P91 or ASTM A213 T91. This product is formulated with a combined Mn & Ni <1.20% to meet stringent customer specifications. Dual Shield B9 is packaged on layer level-wound wire spool baskets to allow the product to be placed in a heated storage oven. In addition, the wire is packaged in a vacuum-sealed foil bag to prevent moisture pick-up until such time the sealed bag has been opened.
